4 speed hump location

[jusglazin]

I'm installing a 4 speed hump in a 66 belvedere. Does anyone have the measurements so I can get it welded in right the first time?

If it is anything like a `68 B-body, which it should be, the hump is nicely fitted to the floorpan and really only works in that spot. You will know it when you have it right, just slide it back and forth until it fits.

The last tunnel extension I installed I didn't weld it down. I made it removable with Dzus fasteners. I wanted to be able to work on or adjust the shifter without having to crawl under the car.
